Find the 3 engineers worth interviewing.

Fonzi ranks candidates on both technical stack and working style. You open a role, you get a shortlist with fit reasoning, not a resume wall.

The Problem

You post a role. 200 resumes arrive. Maybe 3 are worth an interview.

Engineering hiring managers spend 60 percent of their sourcing time filtering out candidates who look right on paper but work the wrong way for their team. Stack credentials are checkboxes. Actual fit is invisible until week three on the job.

How It Works

Post a role. Fonzi handles the match logic. You interview the shortlist.

Three steps from role brief to ranked candidates.

01

Tell Fonzi about the role and team

Describe the stack, how your team makes decisions, and whether you move fast or ship carefully. Takes 8 minutes, not 8 fields.

02

Fonzi matches on two dimensions

The matching engine evaluates candidates on technical stack overlap AND working-style alignment, scoring each combination independently before combining into a single fit score.

03

Review the shortlist with fit reasoning

You get a ranked list of candidates with a plain-language explanation of why each one fits or doesn't. No black-box scores.

What Fonzi Matches On

Stack is necessary. Culture is what makes people stay.

Most recruiting tools stop at keywords. Fonzi maps the three dimensions that actually predict whether an engineer will thrive on your team.

Team Culture

Decision-making style, feedback tolerance, cross-functional comfort. Mapped from your team profile and matched to how candidates describe their ideal working environment.

Working Style

Async vs sync preference, pace expectations, documentation habits. The dimension most likely to cause an early departure when mismatched, and the dimension most tools ignore entirely.

Early Results

From early-access teams who used Fonzi to close their first hires.

We had a critical backend role open for three months. Fonzi gave us 4 candidates in the first shortlist. Two made it to finals and we closed one in 18 days. The stack match was solid, but the culture reasoning was what gave me confidence to move fast.

I used to spend two hours every Thursday morning triaging resumes for open roles. With Fonzi I spend 20 minutes reviewing the shortlist and a reason behind each name. I interview more now, not less, but only the right people.
